To all whom it may concern:

Be it known that I, JOSEPH N. JENNES, a citizen of the United States, residing at Superior, in the county of Douglas and State oflVisconsin, have invented new and use ful Improvements in Notching-Machines, of which the following is a specification.

This invention relates to notching maaction of circular. saws movably disposed in angular relation. One object of the present invention is to provide an organized machi-i ie' of simple and improved construction,comprising two saw carrying units adapted tobe simultaneously operated and whereby two corresponding corners of a seat may be simultaneously notched.

A further object of the invention is to guides may be tilted, thus enabling the notches to be formed obliquely when desired; i

A further object of the invention is to provide a construction whereby the angularly disposed saws may be adjusted about an approximately vertical axis, at right angles to the saw'carrying units, thus enabling the notches to be formed at various angles with reference to the material that is being operated upon.

Still further objects of the invention are to simplify and improve the general consti'uctiol.i and operation of a machineof the character described. I

. With these and other ends in view which will readily appear as the nature of the in Vention is better understood, the same con-' sists in the improved construction andnovel arrangement and combination of parts which will hereinafter be fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the' precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may .be resorted to when desired.

Figs. 12, 13 and 14 are detail sectional elevations showing various positions of the automatic actuating means for the saw car.- riages. Figs. 15, 1(5 and 17 are detail plan views showing specimens of material that has been notched by the improved machine illustrating how notches may be formed differently by said machine.

Corresponding parts in the several figures are denoted by like characters of reference.

The frame A of the improved machine is constructed mainly of cast iron, the component parts being suitably bolted or otherwise connected together. The frame includes side members 1, l and a front bar 2, the latter supporting a bracket 3 having guides 4, at between which a Slide 5 is vertically adjustable, said slide being provided with a nut t3 engaged by a screw 7 which is swivelcd in a ilunge 8' at the lower end of the bracket 3, said screw being provided with a hand wheel 9, whereby it may be manipulated for the purpose of effecting vertical :nljustmcnt ol' the slide 5. Hingedly connected with the slide 5 adjacent to'the upper end thereof is a. work supporting table it) having an arcuate slotted aru l1 engaging a bolt 12 which is associated with a flange 13 projecting 't'orwardly from the slide, said bolt being provided with a clamp nut 14-. by tightening which the work supporting table may be secured in any position to which it may be tilted or adjasled. The work supporting table is provided with work ei'igaging gage members to facilitate the proper adjustment of the material to be operated upon. l

The machine includes two saw carrying chine and .which for convenience ma .te'rmed .th'e'mner side The guides 64: have been shown as being of a cross bar or yoke so as to operate in {The levers F are also provided with rear- 1,o4s,7o5 8 right angles to each other below and in substantially parallel relation to the saw carrying shafts 49 and 50, the latter shafts and related parts is counterbalanced. The being each provided with a pulley or band levers F are slidable or adjustable upon the wheel 58 receiving motion through the meshaft 73 so that when the units of the notch- (hum of a belt or band 59 from the front ing machine are adjusted laterally, the said pulleys 60 upon the shafts 56, 57. Belt 5 levers may be adjusted therewith in order tightening pulleys 61 for the purpose of to preserve the proper relation between the keeping the belts 60 properly tcnsioned are different parts to insure the most effective carried by brackets 62 which are adjustably 1 operation. mounted upon the turret frame. It will be 1 The center shaft 63 is provided with seen that by the construction described, mowheels or disks 7 8 which are slidable upon tion.

Said wheels or disks are shafts. By this construction the saw car located within the frames constituting the ing shafts may be each provided with boxes 1 carriages C, and are movable with said carriages. Each of the wheels 78 carries at opor bearings adjacent to both ends thereof, thus afiording the firm support which is posite sides thereof wrist pins or cranks 79, needed to insure the best results. It is depreferably equipped with anti -friction sired to be understood that instead of using i rollers 81, 852, said anti-friction cranks being means including belts for transmitting moadapted to engage shoes 83, 84 with which tion from the shafts 40 to the saw arbors, j the rear and front slides 69, 68 are, respecany suitable gearing or motions transmitting l tivc'ly, provided. The shoe 83 associated means may. be employed, but as such a with the rear slide 69 is in the form of a U change would be within the scope of the which straddles the wheel 78, the inner limb skilled mechanic, it has not been deemed of said U being secured upon the slide 69, necessary to particularly illustrate the same. while the outer limb is disposed in the path Supported for rotation in suitable bearings of the roller upon the crank it) which is adjacent to the top of the frame A and mounted upon the outer side of the wheel or transversely of said frame is a shaft 63, said disk. The shoe 8i associated with the front shaft being extended beneath the top carslide 68 is disposed in the path of the roller upon the crank 80 of the wheel. It will,

Each 0 the passing into engagement with the shoe 83, slides 68, 69engaging, while the crank 80 is just passing out of engagement with the shoe 84, the slidesavill be moved upwardly until the position sl own in Fig. 13 is reached where the crank 79; is shown as just passing out of engagement 1 with the shoe 83. The crank 80, however. is some distance behind the crank 79, while the shoe 84 is some distance in front of the shine 83. A pause will thus occur in the movement of the slides upon the guide 64 until the crank 80 reaches the point at which it will engage the shoe 84, said pause involving the passage of the crank 80 through approximately 90 degrees or one-quarter of the revolution of the wheel 78. Assuming the wheel 78 to be timed to make from five to j ten revolutions to the minute, it follows thatl a pausevarying in duration from threesec- 'Cw hich are nearest to the center of the maguides 6 L carries two respectively, the front and rear sides of said I mounted upon the side walls of the carriages t guide, said. slides being connected by means unison. The front slide 68 is connected by a link 71 with the upperend of the saw ca'rriage D at the qt j esponding side of the 1 machine so that by the 'reciprocatory movement of the slides 68, 69'-upon the guide 64 j the saw carriage will be reciprocated.

The frame A is provided with upwardly extending brackets 72 affording bearings for t a rod or shaft 73 carrying levers F, each of which has a forwardly extending arm 74 which is connected by a link '75 with one of the links 71 associated with the slides 68.

The shalt t't-i carries a gear wheel 87 mesh ing with a pinion 68 upon a counter shaft- 80 which rcceir motion by a belt 90 from a transmission saat't- 9t which driven by means of a belt 9:3 't'rom the altatt 85.

a main driven From the 't'ore ug description, taken in connection .-lti1 the drawings hereto annexed, the ope ion and advantages of this invention will readily understood by those skilled in tllt' art to which it appertains. The mat-"rial that is to be notched, which may be a womten chair seat, a box seat, a chair arm or other article, is placed upon the table .l t which has been previously adjusted at the rit aisite angle. The units B 01" the machine are adjusted by means of the screw threaded rod lit to place .said units in such position that; the pairs of saws will be stationed at the requisite distance apart. The saw carriage guides may now be tilted so as to present, the planes of the saw at. the desired angle with reference to the work, and the turrets may, likewise, be adjusted to present; the pairs ot? saws at the proper a11- gle. Adjustment is lil e\ e made of the top members or carriages (l wit h TtfOlGllCQ to the bottom members ll of the sa w carrying units, by means of the connta'cting bolts 26, for the IHII'POSO ol lining up the top members or carriages C to the most favorable position with reference to the up and down move ment of the saw carriages when the saw carriage guides have been tilted, so as to avoid a side pull on the saw carriage guides. All of said adjustments will obv ously be do termiued by the character of the work to be pertormctjl, it. being obvious that notches may be 'l'ormcd vertically or at. Various inclinations determined by the tilt, of the supporting table and the tilt of the saw carriage guides and, likewise, that, the side walls l t I l l l t of the notches may be formed in parallel relation to the front and sides of the machine or at various inclinations thereto by proper adjustment of the turrets. It is also evident that by proper adjustment of the units the machine may be adapted to operate upon material of difi erent widths to form notches at the corners of such material. Example-i ot the work have been shown in l 15 to '18, but it is obvious that the machine is capable of performing a great range or variety of work.

After the proper adjustment of the low chine has been etl'ected for the work in hand and the machine has been started in operation. the work will be placed upon the sup porting table which, as stated, is provided with gages whereby the work may be quickly and accurately placed in the proper position. lly the action of the crank disks or wheels 78 on the shaft (33 the saw carriages will be reciprocated upon their respective guides, a. pause occurring at the end of each upstroke or upward movement: of sutlicient duration to enable the material which has cen operated upon to he removed and another pi'ece of material to be substituted upon the work sup 'gorting table, the'tluration of the pause being determined l), the speed at which the machine operator 1 and said pause being approximately one-fourth of the time required for a single complete operation. This action. it will be seen, is entirely automatic and does not in any degree depend upon the operator whose attention will not be distracted but may be devoted entirely to the work in hand, It follows that much greater speed may be at-- taincd than in machines where the tool carrying members are operated by mechanism which requires to be controlled. by the operator, and the out-put may thus be mater-r ally increased without a corresponding increase in the working expenses.
